CORRECTIVE ACTIONS AGAINST DAMAGE TO THE LOWER
FRAME DUE TO LOOSENESS OF THE TORSION BAR.
1.Model Name: SF-2014/2114/2214, SN-1420/1430, Z-800 (For north American)
2.General: This report describes the corrective actions against damage to the lower frame (the
No. : PCE-0012
frame is broken into shutters,in the worst case) which is caused by the Torsion bar on
the front end coming loose and hitting against the left side of the frame unit.
(This symptom occurred at machines manufactured in about September 1996.)
3.Description: We are in the process of investigation into the cause of this trouble. But it has been
confirmed that repeated open/close operation of the upper frame infrequently causes
the tip of the Torsion bar to come loose from the fixing plate, resulting in the Torsion bar
hitting against the left side of the lower frame and damage to the lower frame.
[Normal]
4.Action: A torsion bar fixing bracket is added.

fixing plate,the U-portion with the shank of a screwdriver to shorten the
U-portion (See Fig.3).
Proper attachment
Align the speed nut hole to
the angle hole.
